no new package, dotted-import, graph, action, symbol, artifact, `.wwi`,

`ww run` retains its separate named-operand front door, with its
`.ww`-spelled directory rule specified next. Multiple operands, recursive

format remains 19, and semantic storage format remains 3.
- For `ww run`, an existing selected target whose exact requested spelling
ends `.ww` is a named-source request when symlink-following `stat` reports a
directory. The command rejects it before shared resolution, directory
enumeration, source/import loading, graph/action construction, private run
scratch, producers, or runtime. A requested suffix `_test.ww` has the earlier
exact diagnostic
`ww: cannot run *_test.ww files (OPERAND)\n`; every other such directory has
exact diagnostic `OPERAND is a directory, should be a WW file\n`. Both forms
return status 1 with empty stdout and reproduce the requested operand bytes
unchanged. The rule follows a terminal symlink, includes `.hidden.ww` and
`_hidden.ww` directory spellings, and precedes any malformed package or
missing import inside the directory. A trailing separator does not end
`.ww`; ordinary non-`.ww` directories, dotted logical requests, regular and
missing operands, multiple named operands, and non-directory non-regular
targets retain their established routes. The rejected spelling and followed
target are diagnostic metadata only and create no package/import identity,
graph/action, symbol, artifact, `.wwi`, publication, transaction,
persistence, process, or filesystem owner. Build and all test forms retain
their distinct stat-first directory behavior. Build workdir format remains
18, test workdir format remains 19, and semantic storage format remains 3.
- `import acme.codec;` loads the canonical package `acme.codec`. If that
package declares `package wire;`, the importing file sees its exported names
as `wire.Name`; `codec.Name` is not an additional binding. An explicit alias
